Slip is defined, in this study, as relative motion between the stump skin and the socket. An excessive amount of slip may lead to abrasive injury, inadequate control over socket position and, ultimately, possible loss of the prosthesis. Conversely, lack of slip may conceivably reflect excessive restraint obtained by too tight a fit; implicit are large stump socket pressures. This study was cond...

The objective of this work was to analyze in a parametric study for optimum design solution of prosthetic socket material by finite element method. A realistic three-dimensional finite element model of the PTB socket was developed to find out the stress distribution pattern under physiologically relevant loading condition during normal walking. The CAD model of the rectified socket was collecte...

There have been a variety of efforts demonstrating the use of solid freeform fabrication (SFF) for prosthetic socket fabrication though there has been little effort in leveraging the strengths of the technology. SFF encompasses a class of technologies that can create three dimensional objects directly from a geometric database without specific tooling or human intervention. A real strength of S...

Specialized plant cells arise from undifferentiated cells through a series of developmental steps. The decision to enter into a certain differentiation pathway depends in many cases on signals from neighbouring cells. The ability of cells to engage in short-range intercellular communication permits the coordination of cell actions necessary in many developmental processes. Overexpression of gen...

Long posterior wall (LPW) Charnley acetabular implants are widely used as it is believed that the LPW helps to prevent dislocation. This has, however, not been proven statistically. In a preliminary study of these implants removed at revision marked erosion of the LPW was frequently seen, indicating that repetitive impingement may occur. The influence of the long posterior wall was therefore in...

On most operating systems, the UDP and TCP sockets are the two main types of sockets used to provide transport-layer networking services. However, for several reasons, UDP and TCP sockets are unsuitable for transporting delay-sensitive but error-tolerant streaming data such as the data generated by multimedia streaming applications. In this paper, we create a new type of socket that is suitable...

Two case reports are used to illustrate the signs and symptoms, complications and treatments of chronic socket inflammation due to intraorbital implants. The ophthalmic examination, surgeries and treatments are documented. Two anophthalmic cases that underwent enucleation and multiple orbital surgeries to enhance the anophthalmic socket volume developed pain, intense discharge and contracted ca...

Introduction: Socket grafting offers a predictable, simple way to conserve the buccolingual and mesiodistal dimensions of the future implant site, and various bone-grafting materials using various techniques have shown promising results. Aim: This case presentation describes the use of an absorbable gelatin sponge in the socket preservation procedure. Materials and Methods: A 47-year-old male p...
